LOUIS REIMERS AND NELS ERICKSON, OF DALTON, NEBRASKA.

HARROW TOOTH.

Application filed October 8, 1926.

The present invention relates to improvements in harrow teeth and hasfor its prime object to provide teeth which will prove ef- Iicient inharrowing the ground.

Another very important object of the invention resides in the provisionof an improvement of this nature which is exceedingly simple in itsconstruction, strong and durable, inexpensive to manufacture, thoroughlyreliable in use, and otherwise well adapted to the purpose for which itis designed.

with the above and numerous other objects in view, as will appear as thedescription proceeds, the invention resides in certain novel details ofconstruction and will be hereinafter more fully described and claimed.

in the drawing Figure 1 is a rear elevation of one of the teeth,

Fig. 2 is a top plan View thereof,

Fig. 3 is an end elevation thereof,

Fig. t is a transverse vertical section taken substantially on the line4- 1 of Fig. 2. 7

1n the accompanying drawing I have illustrated merely by way of exampleone of the right teeth as an understanding thereof will make apparentthe construction of the left teeth. Referring to the drawing in detail,it will be seen that the blade is denoted generally by the letter B andthe shank by the letter S. The blade B is of an elongated constructiondisposed substantially horizontally and is substantially triangular incross section as is illustrated in Fig. 4 to-provide a plane uppersurface 5 which is inclined downwardly to one side, a substantiallyvertieal plane surface 6 and a bottom concave surface 7, the surfaces 5and 7 merging into Serial No. 140,296.

a cutting edge 8. The shank S rises and in.- clines outwardly from theblade B and is substantially square in cross section so that it may beattached to the U-bar type of harrow at which time the blade willproject out wardly and rearwardly as will be understood by those skilledin this art so that the cutting edge 8 will be most effective in operation.

It is thought that the construction, utility, and advantages of thisinvention will now be clearly understood without a more detaileddescription thereof. It will be apparent that changes in the details ofconstruction, and in the proportion of the parts may be resorted towithout departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described our invention what we claim as new is:

1. A harrow tooth of the class described including a blade having aplane upper surface inclining downwardly to one longitudinalside edge, aplane upright side surface and a concave bottom surface, the upper andbottom surfaces merging into a cutting edge, a shank rising from one endof the blade.

2. A harrow tooth of the class described including a blade having aplane upper surface inclining downwardly to one longitudi nal side edge,a plane upright side surface and a concave bottom surface, the upper andbottom surfaces merging into a cutting edge, i5 a shank rising from oneend of the blade, said shank inclining outwardly from the blade.

In testimony whereof we aiiix our signa-
